*** The Photography Thread ***

Guess I've got some experimenting to do.

This is the article I was referring to:
" If all you have is a digital camera, then give it a try. Otherwise, use a film-based camera instead. The reason for this is that digital cameras suffer from thermal noise during exposures of more than a second or so. That's why CCD cameras designed for astrophotography have built in Peltier coolers"

MotherGoose is right... that article is very old (with respect to digital camera evolution). Also consider that no high end digital cameras even use CCD anymore these days- they are all CMOS sensors. That may be why I don't even know what he means by "thermal noise"; it is likely an artifact limited to old CCD technology. I think the small point-and-shoots still use CCD sensors, but you won't find them in any pro-level or pro/enthusiast camera these days. CMOS pwns.

Noise control has come a VERY long way since 2001.
